[toaster] greylisting

[Bill Shupp]

In case anyone is curious, I've been investigating Greylisting, a fairly 
new anti-forgery method described here:

http://projects.puremagic.com/greylisting/

I have put together a composite patch of the qmail-envelope-scanner 
program (wrapper for local_scan, both my Martin Dempsey), and a 
qmail-smtpd patch to implement it.  In addition, I put together a 
composite of it with my toaster 0.6-1 patch.  Both are available on 
http:shupp.org.  While I have tested them, I have not put them in 
production.  If anyone cares to help test, please report back to this list.

Cheers,

Bill Shupp
